3'Claims. 1

This invention relates to improvements in pe1- petual calendars whichare adapted to indicate the month of the year, the year, the total number of days in the selected month, and av monthly calendar.

A first object of this invention is to provide a second novel disk consisting of a pair of superimposed circular plateseach having indicia selectively positioned in unison'ata second inspection opening or window for display of the year. The bottom plate includes groups of three numerals indicating the first three numerals ofa given year arranged radially thereon adjacent the edge thereof, and the top: plate includes-circumferentially spaced segmental sight-openingsadjacent the edge thereof and pairs. of sequential circumferentially spaced numerals indicating. the last numeralof a. given yearzadjacentthe inner edges of the segmental sight-openings.

A second object of this invention consists in a monthlyperpetualcalendar consisting vof three rotating disks-having a peculiar arrangement of figures, which is combined with a. card or frame having openings for exposing. portions of the disk.

Yet anotherobject. of. thisinvention is the provision of a novel. perpetual calendar which is capable of use. for many'yearshavinga plurality of rotary disks'which carry legends visible through openings, one. of the disks bearing the numbers of the days of the month arranged insuch'form that when. this disk is: rotated it. may be set to agree with any month. of: any year;.means being also provided for taking careof: leap year.

Yet another object of thisinvention isrto provide a perpetualcalendar' of such character that the rotary disk bearing the monthly calendar indicia may be readily and easily replaced with the proposed world calendar, should the latter calendar be adopted inplace of the present one.

An additional object is the provision of a device of this character which will be simple; and inexpensive in manufacture, highly efficient in use, durable in service, and ageneral improvement in the art.

With the above and other objects and advantages in view, the invention consists in-thedetails of construction to be hereinafter more, fully described and claimed and illustrated in the accompanying drawings, in which Figuretl'is aplan view of thewassembledcalendar of the instant invention;

Fig-urefi is'a plan viewof the month indicating rotary disk.

Reference will now be made to the drawings. In the accompanying. drawings and in the following specification, s imilar reference characters indicate corresponding elements throughout. Generally indicated at 10 is asupport or holder consisting-ofa top member 12 and-a bottom-member l4 secured to each other at appropriate places such as-at' the corners by: means of pins [6 or any other suitable attaching means. Asa result of .the attachment of thetop-member to the bottom member at certain desired places, a space H! is provided between the members for rotatably receiving thereina number of disks to be described hereinafter.

The top member 12 is provided substantially at its center and adjacent its bottom edge with a segmental opening, window or cut-out 29. As seen in Figure 1, above the inner edge of this segmental opening. 2|] the top member 12 carries the spaced letters S, T, W, T, F, and S, indicating the names of the day of the week. Substantially adjacent both sides of, the-segmental opening 28, the top member i2 is provided with a first. transverse opening or window 22 above which is printed the word Month, and a second transverse opening or window 2t above which is printed the Word Year. The top edges of the topand'bottom members i2. and It are provided with a longitudinal arcuate cut-out 25 constituting an opening for the display of the day group as seen in Figure 1. Substantially adjacent the'bottom of the topand botton'imembers l2iand It a pair of arcuate cut-outs 2'3 and 3ilare provided in the side edges of" the top and bottom members.

Rotatabl positioned in the support adjacent the cut-outfit, as. at 32,'is a first disk i 'lhaving axserrated edge .t'ii, a portion. of which extends through'the cut-oat 2:8, upon the face of'which is radially arranged the month of the year, as shown in Figure '6. by rotating the disk 34 at its edge 36, themonth of the year ma be selectively displayed in the openingZE.

A second disk isxprovi'ded which consists of a pair of superimposed plates rotat'ahlypositioned in the support, as at 32?, adjacent the cut-out 3t. The-bottom plate iii is provided with a serrated ed'geAZ, a portion of whichextends-through the cut-out Bil-andearrieson its face, adjacent the serrated edge, groups of three numerals indicating the first three numerals of a given year arranged radially thereon as shown in Figure 4. The top plate 44 is also provided with a serrated edge 46, a portion of which also extends through the cut-out 30. This top plate includes circumferentially spaced segmental side openings 48 adjacent the serrated edge and carries pairs of sequential, circumferentially spaced numerals indicating the last number of a given year adjacent the inner edges of the segmental side openings 48, as shown in Figure 5. Thus, by the proper rotation of the bottom and top plates, the first three numerals and the last numeral of a given year may be selectively positioned for display in the opening 24.

Rotatably positioned in the support and substantially at its center, as at 50, is a central rotary disk 52 which is also provided with a serrated edge 54. This disk is provided with four sets of figures arranged in concentric lines 56 and radial columns 58. It will be oberved that each set of figures is contained in a sector 69 which consists essentially of thirteen radial columns and five concentric zones. These thirteen radial columns, in eiTect, consist of a pair of six columns 62 and 64 separated by an intermediate radial column 65. The figures commence in the innermost portion 68 of the intermediate radial column 66 and are arranged to run consecutively in each of the six columns 62 and 64, the intermediate column 66 having figures in common with the consecutive arrangement provided in the columns 62 and 64. The arrangement of numerals is such that the numerals commence with numeral 1 in the portion or box 68 and proceed in advancing order counter-clockwise in the innermost concentric or first zone. In the next or second concentric zone, the numerals commence with numeral 2 in the extreme lefthand box and proceed in advancing order to the right across all thirteen radial columns. In the next or third concentric zone, the numerals commence with numeral 9 in the extreme left-hand box and proceed in advancing order to the-right across all thirteen columns. In the next or fourth concentric zone, the numerals commence with numeral 16 in the extreme left-hand box and proceed in advancing order to the right across all thirteen columns. And in the next or fifth concentric zone, the numerals commence with numeral 23 and proceed in advancing order.

It will be understood that the window or cut-out 20 subtends seven radial columns.

Also arranged on the disk 52 above each of the zones 62 and 64 and adjacent the serrated edge 54 are pairs of circumferentially spaced day group indicia. As will be seen in Figure 3, these day groups run from 28 through 31. The serrated edge 54, as will be seen in Figure 1, extends through the cut-out 2B.

In practical operation of the device, it will readily be seen that the operator need only position the proper day group in the cut-out 2B and rotate the disk 52 in such manner that the first day of the given month corresponds with the name of the day upon which it falls. The procedure is repeated each month to keep the calendar up to date.
